Spherical pendulum arc type wave power generation device

Abstract

The invention discloses a spherical pendulum arc type wave power generation device which comprises a spherical case, a left floating plate, a right floating plate, a fixing frame, an oscillating rod, a horizontal supporting shaft, a bearing, a steel cable, an arc generator, a heavy punch, a seabed weight and the like. The spherical case is connected with the seabed weight through the steel cable. The left floating plate and the right floating plate are symmetrically welded to the outer wall of the spherical case. The arc generator is fixed to the inner wall of the spherical case through the fixing frame. The bearing is fixedly connected to the horizontal supporting shaft of the sphere center of the spherical case in a sleeved mode. The heavy punch is connected with the bearing through the oscillating rod. The wave power generation device is simple in structure, the number of the middle transmission and conversion processes of wave power is reduced to the minimum degree, and the conversion and transmission efficiency of the wave power is high. Meanwhile, a wave power transmission device and a wave power generating device are arranged in the sealed spherical case, no motion parts are arranged outside the spherical case, and therefore the wave power generation device can not be corroded by seawater easily, and is long in service life and convenient to install, transport, debug and maintain.

Description

technical field [0001] The invention patent belongs to the technical field of marine clean energy utilization, and in particular relates to a spherical pendulum arc type wave energy power generation device. Background technique [0002] Wave energy is a kind of marine renewable energy. Due to its characteristics of high energy density, wide distribution, green and pollution-free, it has been paid more and more attention by countries all over the world. At present, there are some methods for collecting wave energy, such as oscillating buoy type, duck type, raft type, oscillating water column type, over-wave type, etc. However, the above-mentioned wave energy collection devices generally have many moving parts exposed to the marine environment, are easily corroded by seawater, have a short power generation life, and are difficult to transport, assemble and maintain. In addition, the utilization of wave energy is mainly used for power generation, but most wave energy power gen...

Problems solved by technology

However, the above-mentioned wave energy collection devices generally have many moving parts exposed to the marine environment, which are easily corroded by seawater, have a short power generation life, and are difficult to transport, assemble and maintain.

In addition, the utilization of wave energy is mainly used for power generation, but most wave energy power generation devices generally use mechanical gear devices or hydraulic transmission devices to transmit and convert wave energy after capturing wave energy, and their energy transfer efficiency is low.
